Problem is you can't run an RCT and hand out marijuana to teens so you are stuck with biased sampling methods.

- CameronNemo 6y agoYou can do RCTs for adults, though, and teen use of cannabis is trending downward (at least in U.S. states that have legalized medical and/or recreational use).

- edmundsauto 6y agoEasy personal solution is to accept the serious limitations of studies like this. Harder scientific solution is to implement a well designed cohort study that follows people over 20+ years. That's how we know about cardiovascular health. Framingham cohort study.
- alextheparrot 6y agoI haven’t really vetted this study, but it samples IQ prior to use at 9-12 and after use at 17-20 among twins [0]. It concludes that there is no link between IQ scores and usage. More of a “For your interest” reference. Your overall comment is spot on, just because designing a good study is hard does not mean we should accept poorly designed studies as good science. Agency risk unaddressed, science should seek to find the solution to a question rather than an answer. [0] https://www.pnas.org/content/113/5/E500 https://www.pnas.org/content/113/5/E500
